LOUIS PATTERSON, OF SOUTH PUEBLO, COLORADO.

HELICAL FLANGED-WHEEL' MOTOR.

SPECIFICATION formingpart of Letters Patent No. 289,931, dated December11, 1883.

i Application filed June 9,1523. (ModeL) To all whom it may concern.-

Be it known that 1, Louis PATTERSON, of South Pueblo, in the county ofPueblo and State of Colorado, have invented a new and useful Improvementin Helical Flanged Wheel Motors; and I do hereby declare that thefollowing is a full, clear, and exact description of the constructionand operation of the same, reference being had to the annexed drawings,making a part of this specification, and to the letters and figuresthereon.

This invention has relation to improvements in helical flanged wheelsusing steam or water or any other fluid as motive power.

The object of my invention is to devise a wheel which will use eithersteam or water or any other fluid as a motive power, and which will alsoutilize the-expansion of the steam as it passes through the wheel.

The invention consists in the construction and novel arrangement ofthree or-more adj ustable inclined'flanges, made to overlap each otherhalf the diameter of the shaft or more, each independent of the other,yet all working in unison on a common rotating shaft, in com,- binationwith suitable thin plates made to span the distance between the flangesat their nearest points, forming, withthe flanges, a continuous surface,resembling a helical surface, thereby forcing the steam or other fluidto pass through the larger spaces between the flanges.

. The wheel is to be inclosed in atube orcylinder.

In the accompanying drawings, in which similar letters of referenceindicate like parts,

Figure 1 is an end view of the device embodying my invention, and Fig. 2is a side or longitudinal view of the same. Fig. 3 is alongitudinalsection of the casing D along the line y y and a side view of theflanged wheel. I Fig.

0 4 is a longitudinal section of the casing D along the line a: a; and aside view of the flanged wheel in a position at right angles to the oneshown in Figs. 2 and 3. Fig. 5 is a transverse section of the wheel andcasing along the line 2 z.

The letters A A A designate the inclined flanges; B B, the thin platesconnecting them, and O C the shaft. Fig. 1 shows the manner in which theflanges overlap each other.

The operation of the device is as follows: The steam or other fluid,beating against the inclined flanges, rebounds against the plates, thusgiving greater rotary motion and obtaining the full power and expansionof the steam while passing through the wheel. When water or any otherliquid is used, the plates B B "may be dispensedwith. The overlapping ofthe flanges presents a greater surface for the steam or water to beatagainst, and also prevents their free flow through the wheel.

WhatI claim is- 1. The combination of three or more adjustable inclinedflanges placed or strung on a shaft, said flanges made to overlap eachother half the diameter of the shaft, or more, if desired, substantiallyas described.

2. The combination of three or more adjustable inclined. flanges, A, ona common shaft, 0, with thin plates 13 connecting said inclined flangesat their nearest points, the whole inclosed in a cylindrical casing ortube, D, substantially as described, and for the purpose specified. r

In testimony that I claim the foregoing I have hereunto set my hand this14th day of
